I have picked up my iPhone 5c on an upgrade this morning, put in my SIM card but it won't pick up any signal. My 3GS is still working and shows full signal, does anyone have any idea what I am doing wrong....???
Using your T-Mobile SIM card in your old handset, you need to send a text with the word SWITCH to 3333 to start the SIM transfer process. It can take upto 24hrs, but usually takes less than an hour. You will receive a response from EE then your T-Mobile service will disconnect, your 4GEE SIM card should then start working.
